The endangered species of toothed dolphin that’s normally found in the Indus river of Pakistan and parts of India had strayed from its freshwater route and ended up in a busy canal in Pakistan’s southern Sindh province.
The grey dolphin was trapped in a net by the rescue staff and boarded on a truck, where water was sprinkled on it throughout the 82 kilometres-long journey to keep it alive.
“We have to try and get it to the river as soon as possible,” Mir Akhtar Hussain Talpur, an official of the provincial wildlife department, told Reuters news agency during their journey.
The crucial task required the dolphin’s skin to be constantly moist while ensuring the liquid didn’t block its blowholes.
“When we are taking a rescued dolphin to the river, we have to be very careful,” he said.
The blind Indus dolphin is also known as a side-swimming dolphin or bhulan in Urdu and is very similar to the Gangetic dolphins found in India.
The species is now endangered and has declined by 80 per cent since 1870. Now it can only be spotted in one-fifth of the Indus river area it once dominated. As of 2017, it is estimated that there are only about 1,800 dolphins remaining in the area. The species is incapable of forming clear images on the retina, however, they can still sense light.
The Indus dolphin is now the second most endangered cetacean in the world and is listed by the International Union of Conservation of Nature (IUCN) as endangered on their red list of threatened species and by the US government national marine fisheries service under the US endangered species act.
One of the main reasons behind the reducing number of Indus dolphins is reckless fishing which exhausts their food supply. However, the dolphins sometimes also get entangled in fishing nets.
